[aclug-L] Port question

[Wayne White <WWHITE1@xxxxxxxxxxx>]

Greetings,

I was wanting to cause httpd to listen on a port other than 80. I found
the /etc/services file and tried changing the port assignment there. It
had no effect on the port that httpd listens on.

Could someone point me at a howto or man page that would explain
how to accomplish this. It would even be helpful to know what it is
called when alternate ports are used for a given service. Then I could
search for an answer myself.

On a similar theme. Is it possible to have a machine listen for a connection
to httpd on a specific port (other than 80) on one machine and have it
passed through to a specific port on another machine on the same subnet?

For instance, if you wanted to allow http or ftp connections to your network
on a non-standard port, but want the http or ftp server to reside on a machine
other than the one acting as the firewall. I guess sort of a port 
redirection sort
of thing?

I realize that it would probably be a less secure way to do it than using a
server having a separate connection to the Internet, or subnet, than the rest
of your network.

As always, any and all help is greatly appreciated.
